30 EndangeredSpecies UPDATE Vol. 15 No. 3 1998 Northern Assateague Island Restoration Project and the Piping Plover: A Case Study in Endangered Species Act Inter-Agency Consultation Anne Hecht and G. Andrew Moser

Abstract Between September 1995 and May 1992, the U.S. Army Corps of Engineers, Service, and U.S. Fish and Wildlife Service engaged in informal and formal consultation regarding effects on the piping plover of a proposedproject to artificially nourish beaches on the northern end ofAssateague Island, Maryland. Key factors contributing to the success of this consultation included: (I)early and active participation in the consultation process by all federal parties, as well as the Maryland Department of Natural Resources, Worcester County, and Ocean City, (2) availability of extensive high quality baseline information on piping plover habitat use in the project area, (3) explicit inclusion of plover conservation in the project objectives, (4)formulation of a biological assessment, containing detailed assessments of six project alternatives, early in the consultation process, (5)adoption of a relatively restrainedproject design, and (6)incorporation of a monitoring and response plan in the project design. This monitoring and response plan is intended to detect and correct any deleterious effects of the project on piping plover habitat due to lower-than-anticipated overwash frequency. The project, scheduled for construction over a two to three year period, may not be initiated until the autumn of 1999, and actualproject impacts may not be determinable until several years after completion.

The Section 7 consultation dis- cussed in this paper focused on short- term solutions to the perceived short- age of sand on northern Assateague, with the understanding that a long- term plan to rectify the sand budget would follow within five years. The crux of the consultation lies in the following dilemma: available evi- dence suggests that current vulner- ability of northern Assateague Is- land to overwash and breaching is linked to the effects of the jetties. At the same time, however, shoreline stabilization activities, including beach fills and dune construction, have severely impeded natural overwash and inlet formation pro- cesses elsewhere, including at nearby Ocean City itself, at the Assateague Island State Park only a few miles to the south, and at countless other At- lantic Coast beaches. Coastal "pro- tection" projects almost always seek to stabilize beaches, and rarely, if ever, to conserve natural overwash processes that form and maintain preferred piping plover habitats.

Vol. 15 No. 3 1998 Perspective

Going Through the Motions: Fish & Wildlife Service's Critical Habitat Moratorium Heather Weiner

Abstract Critical habitat is an unused but potentially powerful tool to achieve recovery of endangered species. Unfortunately, none of the almost 180 species listed in the last 2 years has had its critical habitat identified or evenproposed. The U.S. Fish and Wildlife Service is using every excuse to avoid designating andprotecting critical habitat as intended by Congress. Service oficials have come out of the closet and admitted that they have no intention of designating critical habitat, unless under court order. But even court orders may have limited influence since Service oficials convinced Congress to limitfunding for new listings and critical habitat designations. With adequatefunding, enforcement, and good public relations, critical habitat designation could provide both public and private resource managers with the clear guidance needed to recover our nation's declining wildlife.

These standards did not meld into one immediately. When it des- ignated critical habitat for the north- ern spotted owl in 1992, the Bush Administration explained that the standards were still different: "The Act's definition of critical habitat indicates that the purpose of critical habitat is to contribute to a species' conservation, which by defi- nition equates to recovery. . .

FWS claims that because critical habitat protections apply only to fed- eral activities, critical habitat designation would result in little benefit for species found on private lands. The court recently rejected this argu- ment in Conservation Coun- cil of Hawai'i v. Babbitt, in which FWS refused to des- ignate critical habitat for 245 plant species in Hawai'i: "[Elven if no federal activ- ity currently occurs on the land, there may be such ac- tivity in the future."

A possibility that the ef- fects were local only comes from a recent report (Semenza et al. 1997) that the nematicide DBCP had been manufactured at a nearby pesticide manufacturing facility. Like the di- eldrin and related biocides from a fac- tory on the Rhine that killed seabirds along the Netherlands coast, and like DDT in factory wastes in Los Angeles and Alabama that grossly contami- nated local environments, DBCP from factory waste could have entered the waters of Lake Apopka. This pesti- cide was banned in the US when it was found to cause sterility among male workers in California (unused supplies were then sent, shamefully, to Costa Rica). Hopefully, experi- ments to resolve this question are currently underway . Smolen and Colborn mention the "feminization and de-masculinization of male birds", referring to a study by Ian Nisbet and his colleagues of common terns of a colony in New Bedford Harbor that is highly contaminated by PCBs (Nisbet et al. 1996).

Harpy Eagle Released in Panama Rainforest

An endangered Harpy eagle (Harpia harpyja), hatched at the San Diego Zoo last October, was successfully released into the Panamanian rainforests in May as part of a captive breeding and re-introduction effort. The national bird of Panama, its population began to decline after the construction of the in 1914. Its slow reproductive rate and large home range made it one of the first species to be virtually eliminated due to human activities (such as deforestation and poaching). Today only a few nesting pairs are known to remain in the Panamanian forests. Since 1989, the San Diego Zoo and The Peregrine Fund have been working together to release young harpy eagles into its native habitat. A young harpy pair, hatched at The Peregrine Fund's World Center for Bird's of Prey in Boise, Idaho, was released earlier this year. A fourth chick, hatched at the San Diego Zoo this January, will be released later this summer, creating two new pairs of harpy eagles in Panama. To avoid imprinting on humans, the eagle was fed via a harpy eagle hand puppet. Now, until the birds learn to hunt on their own, biologists place food high in the forest canopy, where the eagles live. Biologists living in the rainforests near the release site monitor the birds daily. Harpy eagle chicks are dependent on their parents for more than two years so biologists fill the released birds' parent role until they mature. Radio transmitters allow scientists to track the birds as they travel through dense forests.

Rare Bongo Antelope Embryos Implanted into Wild Elands

In a new effort to manage and repopulate species of endangered animals, a team of scientists from the Audubon Institute Center for Research of Endangered Species (CRES) are the first to implant frozen embryos from captive animals in one continent into wild animals in another. The experiment involved freezing 20 microscopic African bongo embryos from CRES and the Baton Rouge Zoo in liquid nitrogen and transporting them to the Mount Kenya Game Ranch, a private wildlife preserve. There, female elands (Tragelaphus eurycerus) had two embryos implanted once it was determined that theiruteruses were at the right stage to accept the embryos (Taurotragus oq~x).(Elands occasionally bear twins, so if both develop there won't be a problem.) Bongos and elands are similar in size but differ in behavior, environment and activity level. As a consequence, the results will be analyzed behaviorally as well as biologically. Since the animals would be reintroduced into the wild from birth, this experiment also negates the criticism of current reintroduction methods-that captive-raised animals may lack survival skills and natural immunity to diseases or suffer from the difficulties of acclimatization. Team members will return to Kenya in February to gauge the results. CRES members hope the work will continue for the next 5-10 years, with two trips a year.
